It is apparent-from the above description of the construction that theyarious partsare comparativel simple in; form and inexpensive tomanu acture and assemble. The parts maybe'made of a lightmetalor alloy so that;

the g fra ne as a whole is lightin weight although of; substantial dimensions insuring the necessary strengthyand rigidity. vThe invention, therefore provides a simple, efficient and inexpensive form of frame having .all the 'essential adjustments which may be quickly. an(l.\co11ve niently, .made, including the interchange ,of the trial .lenses, and the data of. thegvarious adjustments is clearly shown-by efiective indicating means so, that:

when once the adjustments have been .made and the eyesotthc patient properly refracted the data, for. fitting. eyeglasses may all be vread at one timefrom such indicating means.

I claim. as my. invention:

. lyAn ophthalmic trial lens frame comprising a central head portion. provided vwith adjustable means for supporting engagementwith a patients head, limbs car- ;ried bysaid head portion having. substantially horizontal portions extending outwardly below the positions of .the vpatients eyes, a carriage mounted on each ofsaid horizontal portions and adjustable inwardly and outwardly. thereon one independent of another,..members extending laterally from the carriages, lens pockets supported by each of said members; above and at one side of said horizontal portions and temple means carried adj acentthe outer ends of said limbs.

'2. An ophthalmic trial. lens frame com- ..prising a central headportion-provided with means for supporting. engagement witlra patients .head,z-' g limbs g depending from said head portion having horizontal.-portions'extending putwardly-be'low the positions of the 'p'atients eyes, ajcarriagemounted e each ot ei hbr i n e i'Parame sk a d. f h all; I stment one; n depe ident of another; lens 1- tesl etr 1 a9r s;;extending laterall mm gm I said carriages, a plurality of pockets carried by each of said supports, lens adjusting means for certain of said pockets including operating device-s extending through said supports, and temple means connected with said horizontal portions.

3. An ophthalmic trial lens frame comprising a central head port-ion provided with adjustable means for supporting engagement with a patients head, a member fired to said head portion having depending limbs including substantially horizontal portions extending outwardly below the eye positions, independently adjustable carriages mounted upon said horizontal portions, lens pockets supported above said horizontal portions by each of said carriages, means for effecting angular adjustment of the lenses in certain of said pockets including operating spindles mounted for rotation upon the carriages, and temple means connected with said limbs.

l. An ophthalmic trial lens frame comprising a central head portion provided with guide means, a substantially vertical post slidable freely on said guide means, clamping means for securing the post in adjusted position on the head portion, guide means adjacent the bottom of said post, a substantially horizontal bar slidable freely on said post guide means, clamping means for securing said bar in adjusted position on said post, a member fixed to said head portion having depending limbs, including substantially horizontal portions extending outwardly below the eye positions and upwardly turned end portions, independently adj ustable carriages slidable upon said horizontal portions, lens pockets open at their tops and supported above said horizontal limb portions by said carriages, cooperating indicating means on said horizontal limb portions and carriages, and temple means on said limb end portions.
